2nd April 2024:

Recently a customer asked me about the best way to remove the 9V battery from the Fryer-Di Marco Treble Booster.

This is the way I prefer for installing and removing the 9V battery. It is deliberately a tight fit in the pedal so there will be no vibration noises caused by the battery on stage.

The black tool that I am using is 6mm dia Delrin plastic rod which I have shaped at one end into a screwdriver head. This ‘fake screwdriver’ comes in handy all round my workshop. A small screwdriver similar to the yellow one in the video will also do the job well. Hope this video is helpful.

Hooroo, Greg

2nd April 2024:

Marco Giuseppe Di Marco recently sent me this photo of receiving his signature treble booster. Marco also sent photos of his guitar pedalboard and the latest diagram of his guitar rig with ‘Queenshow’ from Slovakia.

Marco used a GoPro camera to film this rehearsal of Queenshow below. It is interesting to see this early rehearsal with the band playing well and sounding great, still with a few rough edges to smooth out for their upcoming tour beginning in mid April 2024.

26th January 2024:

The first 6 Fryer/Di Marco Treble boosters are now completed and tested and are ready for shipping, and I am making more which will be ready to ship next week. Its been very enjoyable cranking out my hackneyed old Brian May licks when I’m doing the testing!

In this photo I am using a Kz Jnr Hybrid (PRS 25″ scale) guitar played through a Vox AC30 amplifier (one of my 100% handmade AC30s from 2010), also a Vox MV50 and one of Manuel Angelini’s amazing sounding Deacy Amp replicas. Cheers n beers, Greg

Around a year ago Marco Giuseppe Di Marco made this video where he demonstrates a prototype of the new Fryer/Di Marco Treble Booster at a live gig with his band, and describes how it works and sounds using his Red Special guitar, pedal board and 2 Vox AC30 amps.

Description of the Fryer/Di Marco Treble Booster:

Handmade by Greg Fryer.

Hand selected and tested BC182L transistor from the same batch of transistors used in the treble boosters made for Brian May by Greg Fryer from 1998 to 2005.

Selected hfe (gain) of transistor considered by Marco Giuseppe Di Marco to sound best with his onstage Vox AC30 rig after many months of live playing tests.

Moderate gain around 31db, sweet detailed balanced sound perfect for use with a Red Special guitar and Burns Trisonic pickups.

Dual use as either a strap mounted or floor mounted treble booster.

Neoprene rubber strip on back for strap use.

New PCB design and PCB layout specially designed for this custom made pedal.

PCB potted in epoxy resin to help reduce unwanted vibration noises which can occur in loud stage environments.

29th May 2023:

Final artwork is now completed for the Fryer/Di Marco treble booster 🙂

======================================================

22nd May 2023:

My apologies that I haven’t yet posted details about pre-ordering the  new Fryer/Di Marco Treble Booster. I have been delayed working on some other urgent things, been working hard burning the midnight oil! Very soon I expect that the details will be finalised so that pre-order details can be posted.

Today I was at the graphic art studio and we were doing artwork mockups for the new pedal’s screenprinting. Below are photos of things we experimented with. At times we compared the new artwork with some of my great older pedals such as the Brian May/Fryer Treble Booster Touring from 2008.

Hooroo, Greg

2nd February 2023:

Happy New Year to all, and an update about the new treble booster. Due to various things late last year its unfortunately taken me longer than anticipated to get the new prototypes completed and shipped off to Marco Giuseppe Di Marco in Italy for his appraisal.

2 of the latest prototypes were posted earlier this week and hopefully Marco will have them for testing in another 2 weeks. At the moment the project is kind of ‘on hold’ until we discuss things further after Marco uses the new prototypes live on stage and compares them to the original pedal.

This January 2023 diagram was kindly provided by Marco Giuseppe Di Marco

========================================================

The ‘Fryer/Di Marco Treble Booster’ is based on a prototype which I recently made for Marco Giuseppe Di Marco from Italy.

Marco uses the new booster mounted on his guitar strap, along with a Shure wireless unit. He is currently touring in Europe with his band “Queen On Fire”.

Please see: https://www.facebook.com/queenonfireofficial

This short video is from soundcheck on 12th August 2022. Marco describes the new treble booster and gives a quick rundown of his rig:

Marco’s prototype pedal uses my Treble Booster Touring circuit with a few custom touches. It has a handmade pcb which has a different layout to the standard TB Touring pedal, it also has a hand selected/tested transistor which is a little more powerful than usual, plus selected components and a few other nice handmade things.

The pedal uses a lightweight diecast aluminium box which is also suitable for mounting on a guitar strap.

I hope to have more photos, soundfiles and comments from Marco Giuseppe Di Marco to post soon.
